Description

Title: Hygiene articles for single use

description

The invention relates to a hygiene article for single use, in particular a diaper, an incontinence product or an incontinence pad, with a front area, a back area and an intermediate area lying in the crotch area of the user of the hygiene article, which is a liquid-tight, at least section-wise, forming the outer side facing away from the body Layer and a layer forming the body-facing inside, at least in the area of an absorbent body arranged below it, and with a fastening system for releasably connecting the back area and front area of the hygiene article in the condition applied to the user and for fixing the article in the rolled or folded state of the used Article when throwing away or disposing, wherein the fastening system has a first fastening section with holding means on the rear area and a second fastening section m it has retaining antidotes on the front area, the first fastening section connecting the rear area and the front area on the second Fastening section can be positioned so that the holding means and holding counter means enter into a mechanical holding connection, and the holding means of the first fastening section are additionally designed to be adhesive.

In order to apply such a hygiene article which absorbs body fluids and excretions, the back area and the front area are placed against the body of the user, the front and back areas at least almost adjoining or overlapping with their side edges, so that using the fastening system front and back area in the best possible fit of the article can be connected to the body of the user, so that leakage of body fluids or excretions supported by further aids, such as elastically stretchable liquid barriers, cuffs and suitable dimensioning of the absorbent body, is prevented. To change the used hygiene article to an unused one, the fastening system is released and the hygiene article containing body fluids and excretions is removed by the user. In order to make the used hygiene article more manageable for disposal, it is usually rolled up or folded from the front area in the direction of the rear area, so that a tangible package is formed which the user, the parents or a caregiver manually grasp and throw into a disposal container can. In order to further prevent the rolled or folded parcel from unfolding when thrown away or afterwards in the disposal container and leading to an unpleasant smell and the leakage of its unpleasant smelling content, the fastening system - as already mentioned at the beginning - is also used to keep the hygiene article in its place to fix curled or folded state. Here, in a known manner, the first fastening section is pressed onto the outside of the rolled or folded packet in such a way that it adheres, sticks or hooks there and prevents the hygiene article from rolling up or unfolding. The first fastening section on the rear area of known hygiene articles is usually provided on an hourglass-shaped section of the rear area, a so-called side flap, or on a fastening flap protruding transversely to the longitudinal direction, that is to say on the sides, which is on the rear area or on the side flaps the back area is attached. The second fastening section on the front area is either not precisely defined and is formed by a surface which has any mechanical acting countermeasures, or it usually extends in the form of a band-shaped transverse area on a collar end section in the front area of the article. The first fastening section can therefore be positioned more or less overlapping in accordance with the shape of the user's body.

Numerous solutions for designing the fastening system have become known. EP 0 321 232 B1, for example, proposes to design the first fastening section in the form of a tab on the rear area such that, in addition to a first section having the mechanically acting holding means, a second section having an adhesive application is provided. In this case, the first section with the mechanically acting holding means serves to close the hygiene article in the state in which the user is wearing it, in that the mechanical holding means cooperate with mechanically acting holding means in the manner of a Velcro fastener. The application of adhesive in the second subsection serves to fix the tab in an adhesive manner to the layer of the article which forms the outer side facing away from the body. If the used article is rolled up or folded from the front area to the rear area, so that the second fastening section comes to lie within the packet, the packet should be fixed in cooperation with the adhesive second section with the film-like smooth outer surface of the article. This fastening system proves to be disadvantageous insofar as the first fastening section, ie the Fastening tabs, according to which two sections must be very large or long. The material requirement is correspondingly large and the tabs protruding to the side interfere with the handling of the article and look inconspicuous. A defined holding force of the fastening system cannot be achieved, since when it closes there is a more or less large overlap or contact of the adhesive second section with the surroundings of the second fastening section on the front side and accordingly a more or less strong additional adhesive connection in addition to the intended one mechanical connection of the detent and detent comes. This vagueness must be seen as disadvantageous.

EP 0 321 234 AI takes a different approach by separately providing a striking section with mechanically acting retention means on the layer forming the outer side facing away from the body, which cooperates with the first fastening section in the rolled-up or folded configuration of the article. An adhesive application is not provided here. The arrangement of this further mechanically acting impact section on the outside of the article is complex and the handling when folding the article is difficult and requires attention since the fastening sections have to be positioned exactly with respect to one another. In this situation, experience has shown that this attention can hardly be given, since when nursing small children there is often only one hand available for quickly folding the diaper and, if possible, an unused hygiene article should be pushed into the toddler at the same time.

From EP 0 393 953 B1 it is known to also use an adhesive application on the outer side of the bandage facing the article of clothing to attach a hygiene article in the form of a sanitary napkin to a piece of clothing. So that the bandage can be fixed on the textile material of the garment without slipping, are on the the outside of the bandage, which has an adhesive layer, is provided with tapering projections which are pressed into the textile material and thus immovably fix the bandage. Such a design of the first fastening section of the hygiene article in question should, however, prove to be unsuitable, since interaction with a film-like outer side of the article facing away from the body would not be possible in this case.

With WO 96/25905 it was proposed to partially provide the first fastening section or the mechanically acting hook-like holding means and at the same time also the second fastening section with mechanically acting holding counter means with an adhesive application. When connecting the back part and the front part in the state in which the article is placed on the user, both connection mechanisms, that is to say mechanically holding or engaging behind on the one hand and adhesive on the other hand, are intended to interact in combination in order to form the desired fastening. The force required to release the connection is broken down into a shear force projected onto the plane and a pulling force acting perpendicular to the plane, which force is primarily attributed to the mechanical connection mechanism and, more particularly, the adhesive connection. According to the teaching of this document, the term “adhesive material” is understood to mean those materials which form an adhesive connection only with other adhesive materials. Because both the first and the second fastening section are additionally provided with such an adhesive material, a strong adhesive force that supports the mechanical connection is to be achieved. The problem of fixing the used hygiene article in a rolled-up or folded configuration is not addressed in this document.

The object of the present invention is to improve a hygiene article of the type described in the introduction in such a way that when the article is placed on the body of a user, the article always sits correctly and also secure connection of the front and back area can be achieved and that the used article can be fixed in a configuration that is suitable for disposal and is easy to handle.

According to the invention, this object is achieved by a hygiene article with the features mentioned at the beginning,

a) that the holding counter means (90) of the second fastening section (64) are adhesive-free and for closing the hygiene article in the state in which the body is in contact with the holding means (72) of the first fastening section (62), a mechanical holding connection with a first peel-off - Develop a force of more than 1 N / 25mm, and

b) that the holding means (72) of the first fastening section (62) is so adhesive and the layer (44) forming the outside (42) is at least in the vicinity (100) of the second fastening section (64) on the front region (4) so smooth that the retaining means (72) of the first fastening section (62) adhere there with a second peel-off force which is less than the first peel-off force, and

c) that the retaining means (72) of the first

Fastening section (62) so adhesive and the layer (44) forming the outside (42) is at least in the central region (8) so smooth that the holding means (72) of the first fastening section (62) thereon with a peel-off force of Adhesive at least 0.1 N / 25mm to fix the hygiene article in a rolled up or folded configuration.

With the progressive development of the hygiene products, a design that is better suited to the body shape is achieved. The invention is based, inter alia, on the knowledge that, with an optimal design, a perfect fit of the hygiene product and thus a safe leakage protection and pleasant wearing feeling free of pinching is only given if the fastening system, ie the first and second fastening section, are positioned and fixed correctly in accordance with the manufacture of the article. The hygiene article is thus designed according to the invention in such a way that a user of the hygiene article, the parents or nursing staff, is forced to use the fastening system, ie the, when putting on the hygiene article

Align and position the fastening sections on the rear and front areas so that the

Fastening sections at least almost completely overlap or overlap each other in order to provide the required holding force. This is achieved by the features according to the invention mentioned above. If the fastening system is used carelessly, so that the first fastening section overlaps only slightly with the second fastening section or even lies at an offset position, for example below a second fastening section designed as a band-shaped collar, the design of the fastening system according to the invention makes the user without Realize further that sufficient positioning of the system is not achieved with this positioning. He will detach the first fastening section from the point just selected and position it on the second fastening section, which can be easily identified with some attention.

With the invention it was also recognized that when using the fastening system for fixing the hygiene article in a configuration suitable for disposal, a peel-off force of at least 0.1 N / 25 mm, preferably of 0.5 to 1 N / 25 mm is sufficient. A further advantage of the configuration according to the invention results from the fact that for the purpose of this fixing, no additional separate, difficult-to-use impacting means has to be provided, but rather that the respective first fastening section is designed such that it can be placed anywhere on the outside of the central region, possibly also adequately adheres to the back area in the manner specified. It is expressly pointed out that the nature of the layer forming the outside can be the same over its entire surface. In this case, the first fastening section holds in the vicinity of the second fastening section with the same second peel-off force of at least 0.1 lN / 25 mm as on the rest of the outside of the layer, in particular the middle region and the rear region.

The holding forces referred to above as peel-off forces are defined and measured in the manner described below. A 25 mm wide test strip, a material that forms the first fastening section with its holding means, is provided for the test. This test strip is applied to the counter surface to be tested under a contact pressure of 2 kg using a rollover device. This is either the second fastening section or the outer layer of the product, which forms the surroundings of the second fastening section and preferably also the rest of the outer side of the product, such as, for example. the central area to which the first fastening section for disposing of the rolled-up hygiene article is applied in order to fix the rolled-up or folded configuration. This. The counter surface is applied to a rigid holder. The holder is fixed in a tensile tester and the test strip is clamped to a pull jaw, so that a pull-off angle of 150 ° results, which is slightly reduced by a few degrees when pulling off. By measuring the holding force referred to as the peel-off force, the test strip, that is to say the first fastening section, is pulled off the counter surface at a constant speed. The measured peel-off force is recorded as a function of the path.

It is now possible in a particularly advantageous manner to form the layer forming the outside of the article in any desired manner, in particular with an essentially smooth film-like surface or with a fibrous, in particular textile-like surface. In the former case the remaining holding force, which is not satisfactory in the area around the second fastening section, but is still sufficient in the central area for the purpose of disposal, is essentially determined by the adhesive effect. If the layer forming the outside of the hygiene article has a fibrous, textile-like surface, the influence of the adhesive effect is reduced and that of the mechanical connection mechanism is brought to the fore. In such a case, the outside of the article in the vicinity of the second fastening section on the front region will nevertheless still be so smooth that the second peel-off force occurring there is preferably substantially below the first peel-off force.

It goes without saying that the mechanically acting holding means of the first fastening section can be completely or partially covered with adhesive. It is also pointed out that the mechanically acting holding means can also consist of adhesive material.

Preferred embodiments of the holding means and the formation of the second fastening section with the holding counter means and the layer of the hygiene article which forms the outer side facing away from the body result from the attached protection claims.

It has proven to be particularly advantageous if the holding means are formed by projections with end areas that can reach behind or reach behind and have a geometry or dimension as specified in the claims. The second fastening section is a fluff-like fibrous band material which preferably runs along the collar end section of the front region. This can be a textile material, such as a woven or knitted fabric, but nonwoven materials based on nonwovens are preferably used. Such a fleece-based material generally has a two-layer structure a backing layer, which can consist, for example, of a film, a spunbonded fabric or a meltblown nonwoven or the like, and a loop layer forming the retaining antidotes, for example a carded web or a spunbonded fabric, into which the retaining means of the first fastening section can engage and get caught there.

In addition, the fluffy material can have a printed image that can be applied either to the carrier layer or directly to the loop layer or to a third, in particular film-like layer, which is then preferably positioned between the carrier layer and the loop layer.

It was found that the design of the fluff-like, fibrous material is of particular importance for the holding force between the first fastening section of the rear area and the fluff-like material of the front area. Fiber strength, fiber length, basis weight of the fluffy fibrous material are preferably carried out according to the information in the protection claims.

It has turned out to be particularly advantageous if the fluff-like fibrous material has elevations which form loops arranged in a regular pattern and have the dimensions as specified in the attached claims for protection. The elevations forming the loops can advantageously be achieved by heat sealing the fluffy fibrous material against the carrier layer. A 3M Deutschland GmbH, Neuss, DE company can obtain a flat material composite consisting of a film-like carrier layer and a fluff-like fiber layer, which has a parallel, endless wave pattern of elevations due to the application of heat-seal embossments which extend parallel to one another. A flat material composite with diamond-shaped heat seal embossments can be obtained from Corovin GmbH, Peine, DE.

In the layer forming the outer side facing away from the body, the can have a smooth surface or at least a certain textile, fibrous character imparting surface, it is a film or preferably an at least two-layer, in particular three-layer nonwoven film laminate. The three-layer laminate preferably comprises a film-like meltblown layer forming the outside, an adjoining spunbonded layer and an inside film layer (spunbond meltblown laminate).

Figure 1 shows a hygiene article in the form of a diaper 2 for a small child or for incontinent people. The diaper 2 is arranged in the crotch area between the legs of a user and is then placed upwards towards the user's hips against the body and fixed in a manner to be described in more detail in such a way that a type of panties is formed.

The diaper consists of a front area 4, a back area 6 and a middle area 8 lying in between and lying in the crotch area of the user of the diaper. The front area 4, the middle area 8 and the back area 6 are arranged in a longitudinal direction 10. The central region has two longitudinal edges 12 which run in the longitudinal direction 10 and which curve outward toward the front region 4 and towards the rear region 6 in order to merge into side flaps 14, 16 on the front region 4 and on the rear region 6. The side flaps 14, 16 extend with their longitudinal edges 18, 20 again essentially parallel to the longitudinal direction 10, but this is not absolutely necessary. The front region 4 and the rear region 6 furthermore have a transverse edge 26, 28 which runs transversely to the longitudinal direction 10 and delimits a collar end section 22 or 24 which comes to rest in the hip region of the user when the diaper 2 is in the fitted state. The respective longitudinal edge 12 of the diaper 2, with its course curved outward to the side flaps 14, 16, defines a respective leg opening when the diaper is in the applied state.

An inner surface 30 which forms the body-facing side of the diaper 2 is formed by a liquid-permeable surface layer 32 which extends in the longitudinal direction from the transverse edge 26 to the transverse edge 28. Below the 1, a suction body 34 is provided which, as can be seen in FIG. 1, has an hourglass-shaped circumferential shape and extends from a transverse edge 36 in the front region 4 to a transverse edge 38 in the rear region 6, the transverse edges 36, 38 being a distance apart from one another Have magnitude of cm to the respective transverse edge 26 or 28. The absorbent body 34 is therefore completely covered in the longitudinal direction 10 by the upper liquid-permeable surface layer 32. The surface layer 32 has two straight longitudinal edges 40 which are spaced from one another such that they overlap the absorbent body 34 in the central region 8 transversely to the longitudinal direction 10, whereas in the front region 4 and in the rear region 6, approximately in the region of the side flaps 14, 16, the hourglass-shaped absorbent body 34 projects transversely to the longitudinal direction 10 below the surface position.

A layer 44 forming the outer side 42 of the diaper 2 facing away from the body is formed by a film-like layer 46 which is liquid-tight at least in a central longitudinal region 45 and which delimits the absorbent body 34 from the outside. In order to fix the extension and positioning of the absorbent body 34, the upper liquid-permeable layer 32 is connected to the outer liquid-tight layer 44 along the transverse collar end sections 22, 24 and along those sections of the longitudinal edges 40 which overlap the absorbent body 34 transversely to the longitudinal direction 10 , any connections by means of glue or by heat sealing or the like.

As can also be seen from FIG. 1, first outer and second inner known per se extend at a distance from the longitudinal edges 12 and in the longitudinal direction 10

Elastification means 48 and 50, the outer and inner

Form leg ends. The outer and inner

Elasticizers are overlaid by a hydrophobic cover layer 52, which extends along the longitudinal edge 12 of the diaper from one transverse edge 26 to the other transverse edge 28. Cross to

In the longitudinal direction 10, the cover layer 52 extends from the outside inwards to the inner elastic means 50 and forms there with inclusion or inclusion of the inner

Elastification means 50 a fold 54 by an inner longitudinal edge portion 56 of the cover layer 52 is folded over and glued to the lower side of the cover layer 52. In the middle region 8 of the diaper 2, under the pretension of the inner elasticizing means 50, a cuff 58 is formed which stands up in the direction of the body surface of a user. This cuff 58, which is provided in the area of both leg ends, extends into the front area 4 and into the rear area 6, in order there in the longitudinal direction 10 at the level of the side flaps 14, 16 by folding the inner side of the fold 54 or the cuff 58 against the inner surface 30 of the liquid-permeable surface layer 32 glued, in particular to be sealed there. The inner elasticizing means 50 ends in the longitudinal direction at a distance from the transverse edges 26, 28 of the diaper 2 and is also fixed in the area of the folded and fixed fold 54 so that it can exert a tension in the longitudinal direction so that the cuffs 58 "stand up". The outer elasticizing means 48, under longitudinal tension, are glued, in particular sealed, between the cover layer 52 and the liquid-impermeable outside film-like layer 46. They also end in the longitudinal direction 10 at a distance from the transverse edges 26, 28, which is, however, not absolutely necessary, but creates a tension-free collar end section 22 or 24.

To fasten the diaper in the state in which the user is wearing it, a fastening system, designated overall by reference numeral 60, is provided (FIG. 3). The fastening system 60 comprises a first fastening section 62 on both sides of the rear area 6 and a second fastening section 64 forming a type of target surface for the first fastening section 62, which in the form of a band-shaped strip 66 in the front collar end section 22 on the outside of the front part 4, to be described in more detail is appropriate. The respective fastening section 62 is formed by a band-shaped tab 68. The tab 68 is approximately Y-shaped and extends from the longitudinal edge 20 of the respective side flap 16 to the top or bottom of the diaper 2 and is glued there. The tab 68 has, on the side 70 which faces outward towards the body (see FIG. 1), mechanically acting retaining means 72 (FIG. 4, which shows a schematic sectional view of a section of the tab 68 having the retaining means 72). The mechanically acting holding means 72 are provided with projections 74 which are T-shaped or mushroom-shaped in the sectional view, with areas 76 which can engage or engage behind. A single projection 74 of this type is shown enlarged in FIG. Such a projection comprises a stem 78 extending from a base 77 of the tab 68 and a head 80 forming the free end. The mechanical holding means 72 or projections 74 have an adhesive application 84 in the form of part of their surface 82 or on the entire surface 82 of a pressure-sensitive adhesive having a permanent adhesive force (not shown in FIG. 5). Instead of applying an adhesive, the holding means 72 or projections 74 can also be formed entirely from a material having permanent adhesive properties.

It would also be conceivable that a further adhesive application 85 is provided in the area between the projections 74 on the base 77, as a result of which the adhesive force can be increased further if the tab 68 is pressed with great force onto an area to which the adhesive is adhering Shows effect. It can then - as indicated in FIG. 4 - prove to be advantageous if the thickness of the further adhesive application decreases transversely to the longitudinal direction 10, that is to say in the direction of the free tab end, so that when the tab 68 is released, the free tab end is more easily released can be.

As can be seen in FIG. 5, the projections 74 have a total height H1 of 0.61 mm, a distance H2 between a lower edge 86 of the area 76 that can be gripped behind and the Base area 77 of the tab 68 is 0.37 mm. The thickness D of the stem 78 and the head 80 is 0.3 mm. The width Bs of the trunk is 0.21 mm in the case shown and the width Bh of the head 80 is 0.55 mm. The angle a, which the trunk 78 forms with the surface 70, is 90 °. According to a preferred embodiment, 87 projections per cm ^{2 of} the base 77 of the tab 68 are provided. It is pointed out that the shape described above corresponds to a preferred embodiment, but that other designs of the projections are also possible.

FIG. 6 shows an embodiment of a mushroom-shaped retaining means 72 'with a circular cross section of the head and trunk, the head 80' of which has a width Bh 'of 0.4 mm compared to a width of the trunk 78' Bs' of 0.25 mm. The height of the head H 'compared to the base is 0.53 mm.

FIG. 7 shows a third embodiment of retaining means 72 ″, which are Y-shaped in view. The holding means 72 ″ comprise a stem 78 ″ with a thickness of 0.15 to 0.25 mm. The head 80 ″ formed at the free end of the legs forms a kind of table surface for the adhesive to be applied. This table surface has a preferred dimension a, b of 0.27 by 0.25 to 0.35 mm. The head 80 ″ is designed such that, as can be seen from FIG. 7, it overlaps the trunk 78 ″ in two opposite directions and thus forms a region 76 ″ that can be gripped behind. The height H '' of the head above the base 77 '' is approximately 0.32 mm. The extension Y of both legs of the Y-shaped holding means 72 ″ is 0.75 mm. In this preferred embodiment, both the flattening and the course of the two free legs of the Y shape form a region that can be gripped behind. At the same time, the table-like flattening is particularly suitable for applying adhesive. The preferred density of the Y-shaped protrusions is about 250 / cm ² . The first mentioned in connection with Figure 3

Fastening section 62 is pressed onto the second fastening section 64, that is to say onto the strip 66 in the front region 4, in order to close the diaper 2. FIG. 8 shows a sectional view of the strip 66. This has a two-layer structure with a carrier layer 88 and a loop layer 92 made of a fluffy, fibrous material 94, which forms a retaining counter-means 90. The carrier layer can preferably be a film, a spunbonded fabric or a meltblown nonwoven. The loop layer 92 can advantageously be formed from a carding fleece or a spunbonding fleece, into which the holding means 72 of the first fastening section 62 can engage and hook. For this purpose, the loop layer 92 has loop-forming elevations 96, which are produced in that the nonwoven material 94 which is applied to the carrier layer 88 and preferably forms a fleece is fixed in sections against the carrier layer 88 (reference symbol 98). The fixation can be done along parallel lines - as shown in Figure 8 - or in the form of diamond, triangle or circular patterns by a heat sealing process.

The design of the loop layer 92 is of great importance for the adhesive force. In the exemplary embodiment shown in FIG. 8, the elevations 96 form endless waves, their width Bw being 2 to 5 mm and the width of the fixed surface 98 transverse to their extension Bf being 0.2 to 5 mm. The height H of the elevations 96 is preferably 0.2 to 5 mm. A fiber thickness of the fluffy material 94 of 6 to 9 dtex and a fiber length of 4 to 5 cm are preferably selected. The basis weight of material 92 is 40 to 70 g / m ² . If the tab 68 is correctly positioned on the strip 66 and lightly pressed on to close the diaper, the projections 74 engage in the loop layer 92 and hook there mechanically, with a peel-off force of 2 to 4 N / 25 mm, is preferably achieved to ensure that do not accidentally open the diaper.

To force the user of the diaper to close the diaper correctly, i.e. To correctly position the first fastening section 62 on the second fastening section 64 so that an optimal fit of the diaper can be achieved is the environment 100 of the second

Fastening section 64 or the strip 66 formed so that the first fastening section 62, when it is positioned and pressed thereon, has a second peel-off force which is less than the first peel-off force. This second peel-off force is determined in the case of a film-like very smooth outside 42 by the adhesive application 84. However, it is also possible to provide the layer 44, which forms the outer side 42 of the diaper facing away from the body, with a certain textile character. In such a case, however, it is necessary that the outside 42, at least in the vicinity 100 of the second fastening section 64, is designed to be smooth or smooth and that the retaining means 72 of the first fastening section 62 are adhesive in such a way that a peel-off force of 2 N / 25 mm , in particular not exceeded by 1 N / 25mm. If a user of the diaper does not correctly position the first fastening section 62 in relation to the second fastening section 64, but rather in the environment 100, the very low adhesive force in the environment 100 of the second fastening section 64 means that he is immediately informed of his mistake and becomes the first fastening section Pull off 62 and position it again, this time in the correct way, in relation to the second fastening section 64.

The layer 44 forming the outside 42 is in the form of a spunbond meltblown laminate (FIG. 9), which comprises a film-like meltblown layer 102, an adjoining spunbonded nonwoven layer 104 and an inside film layer 106. If the used diaper 2 is rolled up or folded for disposal, a user can press the first fastening sections 62 or tabs 68 anywhere on the outside - in the rolled-up state of the diaper, the central region 6 will then be the target area - so that these adhere to it at least with a peel-off force of at least 0.1, preferably from 0.5 to 1 N / 25 mm. This relatively low adhesive force has been found to be sufficient for the purpose of securing the diaper in the rolled or folded state and throwing it into a container in this configuration.
